Rotary drum fertilizer granulator - wet granulation equipment

Rotary Drum Granulator as one of the key equipments in fertilizer making process, The cylinder body adopts special stainless steel or rubber plate lining structure. It can remove scar and peel burl automatically It has the advantages of high intensity of granule, high production, erosion proof, abrasion proof, low energy consumption, long service life, convenient operation and maintenance etc. Remark: If the formulation, process and raw material are different, it will affect the yield, grain rate and the diameter of the grain.

Why Rotary Drum Fertilizer Pelletizer?

1.Polyethylene plastic plates are fixed in inner drum to prevent sticking and protect drum from corrosion.
2.Drum is placed obliquely in brackets which is made of robust carbon steel plates and channel beam.
3.Inside the drum wall is shoveling plates for easy granulating and cleaning.
4.The rotary drum granulator is made from our vertical lathe, which is strong and solid enough for granulating.
5.Rational design. Motor drives gears and gears drives rotary drum working.
6.Energy conservation,steady granulating process, little noise.

Reasonable Structure on Tongda Rotating Granulators

--Granulator bracket. The whole rotating part of the Tongda fertilizer granulator machine which bears large force is supported by bracket, therefore the compound fertilizer productionmachine adopts medium carbon steel plates,channel beam material which are welded and satisfies strict quality standard.
--Drive part. The gear frame is welded of high quality channel beam. The main motor in gear frame and reduction gears are both ISO National Free-inspection Product. Motor drives belt sheave,trianguler belt and reduction gears and offers power to granulator.
--Large gears. Fixed on granulator and meshes with small transmission gears to drive the whole machine working in the opposite direction. High-tech wear-resisting materials extends granulator service life.
--Rolling belt. Fasten on both sides of granulator for supporting.

Working principle of drum pelletizers

This fertilizer granulation equipment is a machine with wet granulation methods. Raw materials to be granulated can be steam, gaseous ammonia, phosphoric acid, ammoniacal solution, ammonium phosphate slurry, and triple superphosphate slurry. After these solid fertilizer particles enter into the rotary drum, they will make reciprocating movement under functions of gravity, centrifugal force, and friction force between fertilizers. With the rotary movement of the drum, produced materials spray onto the surface of granulation nucleus. Then the coating layers become thicker and thicker until produced materials are granulated into required dimensions. Finally, those obtained products are spilled out from the discharging hole.
